时间:2023-02-09 20:17:50

功能:获取或设置指定形状内部绘制方式的Brush.
命名空间:System.Windows.Shapes
它对应的C#语法为
public Brush Fill {get;set;}
C++为

public:
property Brush^ Fill {
    Brush^ get ();
    void set (Brush^ value);

此示例演示如何使用 Fill 属性来设置 Ellipse 元素的背景颜色。

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel>
<Ellipse Fill="Red" Width="100" Height="100"/>
</StackPanel>
</Page>

对应的C#代码

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
using System.Windows.Shapes;

namespace SDKSample
{
    public partial class SetBackgroundColorOfShapeExample : Page
    {
        public SetBackgroundColorOfShapeExample()
        {
            // Create a StackPanel to contain the shape.
            StackPanel myStackPanel = new StackPanel();

            // Create a red Ellipse.
            Ellipse myEllipse = new Ellipse();

            // Create a SolidColorBrush with a red color to fill the 
            // Ellipse with.
            SolidColorBrush mySolidColorBrush = new SolidColorBrush();

            // Describes the brush's color using RGB values. 
            // Each value has a range of 0-255.
            mySolidColorBrush.Color = Color.FromArgb(255, 255, 0, 0);
            myEllipse.Fill = mySolidColorBrush; 

            // Set the width and height of the Ellipse.
            myEllipse.Width = 100;
            myEllipse.Height = 100;

            // Add the Ellipse to the StackPanel.
            myStackPanel.Children.Add(myEllipse);

            this.Content = myStackPanel;
        }

    }
}
